- the packing 50 is held on the upper surface of the upper end 28 a of the abutment rib 28 of the holder 20 to ensure waterproofness.
- the lock projection 52 interferes with the upper end 28 a of the abutment rib 28 , and the misassembled state of the packing 50 is detected.
- the upper end 28 a of the abutment rib 28 of the holder 20 can easily hold the packing 50 assembled to the cover 40 and detect misassembly.
- the oval hole formed in the fastening portion of the crimping terminal is a bolt insertion portion into which a bolt is inserted.
- the bolt insertion portion is not limited to the oval hole with the oval shape, but may be a hole having a circular shape or may be a C-shaped opening.
- the base with cylindrical oval shape made of metal or hard resin and configured to fasten the crimping terminal is fitted and fixed in the cylindrical oval section of the holder.
- a metal base may be insert-molded into the holder, or a resin base may be integrally molded with the holder.
